How to find grams used of methanol? The molecular weight in g/mol is 32.04 and the density is 0.791. Also 25 mL of methanol was used. How to convert this to grams?
mass = volume x density. You know mass and density, substitute and solve for grams.
To find the number of grams of methanol used, you need to consider its density and volume. Here's how you can calculate it:
Step 1: Convert the volume from milliliters (mL) to liters (L):
Since 1 L is equal to 1000 mL, divide the given volume by 1000 to convert it to liters:
25 mL ÷ 1000 = 0.025 L
Step 2: Use the formula for density to calculate the mass in grams:
Density = Mass / Volume
Given density: 0.791 g/mL
Volume: 0.025 L
Rearrange the formula to solve for mass:
Mass = Density × Volume
Mass = 0.791 g/mL × 0.025 L
Step 3: Calculate the mass in grams:
Mass = 0.791 g/mL × 0.025 L = 0.019775 g
Therefore, the number of grams used in 25 mL of methanol is approximately 0.019775 g.
